Description
Antrieb für den Massenausgleich zweiter Ordnung an Brennkraftmaschinen Die Erfindung betrifft einen Antrieb für den Massenausgleich zweiter Ordnung an Brennkraftmaschinen oder dergleichen mit zwei parallel zur Kurbelwelle gegensinnig zueinander umlaufenden Hilfswellen mit Gegengewichten, welche von einem Zahnrad auf der Kurbelwelle aus über eine Kette angetrieben sind. Drive for second order mass balancing on internal combustion engines The invention relates to a drive for mass balancing of the second order Internal combustion engines or the like with two parallel to the crankshaft in opposite directions mutually rotating auxiliary shafts with counterweights, which are driven by a gear are driven on the crankshaft from via a chain.
Bei derartigen Antrieben können infolge der von der Kurbelwelle herrührenden Torsionsschwingungs-ausschläge am Antriebszahnrad teilweise erhebliche Beschleunigungen auftreten, weshalb bei einer star.In such drives, as a result of the crankshaft caused Torsional vibration deflections on the drive gear can accelerate considerably occur, which is why with a star.
ren Ausbildung des Antriebs infolge der Massenträgheit der Ausgleichs.ren training of the drive due to the inertia of the compensation.
gewichte eine große Beanspruchung der Antriebskette erfolgt, die eine reichliche Bemessung erfordert. Eine derartige Maßnahme ist im Hinblick auf das hohe Gewicht jedoch unerwünscht.weights there is a great stress on the drive chain, which is a requires ample sizing. Such a measure is with regard to the however, high weight is undesirable.
Die Aufgabe der vorliegenden Erfindung besteht nun darin, den Einfluß der Torsionsschwingungen der Kurbelwelle auf das Antriebsrad auszuschalten, In diesem Fall sind dann nur die beim Hochfahren oder Abbremsen des Motors auftretenden Beschleunigungskräfte der Ausgleichsmassen von der Kette zu übertragen, so daß deren Abmessungen verringert werden können.The object of the present invention is now the influence to turn off the torsional vibrations of the crankshaft on the drive wheel, in this The only case is the acceleration forces that occur when the motor is started up or braked to transfer the balancing weights from the chain, so that its dimensions are reduced can be.
Man erreicht dies nach der Erfindung dadurch, daß das Antriebszahnrad drehelastisch auf der Kurbelwelle angeordnet ist, derart, daß die bei konstanter Motordrehzahl auftretenden kleinen Momente elastisch, die bei Beschleunigungen verursachten größeren Momente starr übertragen werden. Durch diese Maßnahme, d. h. die Verbindung des Antriebszahnrades mit der Kurbelwelle über eine Anzahl über den Umfang verteilter omegaförmig gebogener Drahtfedern und die Anbringung von Mitnehmerbolzen an der Kurbelwelle, welche in Langlöchern des lose drehbar gelagerten Antriebsrades geführt sind, sind bei konstanter Motordrehzahl durch die Elastizität lediglich die Reibungsverluste des Antriebes auszugleichen, während die Mit nehmerbolzen die Übertragung der Beschleunigungs- und Bremsmomente übernehmen. Durch die extrem weiche Ausbildung des elactischen Gliedes werden zudem Schwingungen von den Ausgleichsgewichten sicher ferngehalten. Die erfindungsgemäße Ausbildung der Federn gewährleistet darüberhinaus die Unterbringung einer großen Drahtlänge auf kleinem Raum und damit eine hohe Elastizität.This is achieved according to the invention in that the drive gear is arranged in a torsionally flexible manner on the crankshaft in such a way that the at constant Engine speed occurring small moments elastic that caused during accelerations larger moments are rigidly transmitted. By this measure, i. H. the connection of the drive gear with the crankshaft over a number distributed over the circumference omega-shaped bent wire springs and the attachment of drive pins on the Crankshaft, which is guided in elongated holes of the loosely rotatably mounted drive wheel are, at constant engine speed, only the friction losses are due to the elasticity to compensate for the drive, while the driving pins transfer the acceleration and take over braking torques. Due to the extremely soft training of the elactic In the link, vibrations are also safely kept away from the balance weights. The inventive design of the springs also ensures accommodation a long wire length in a small space and thus a high degree of elasticity.
Es ist zwar bekannt, bei Antrieben für den Massenausgleich zweiter Ordnung die Wirkung von Drehschwingungen der Kurbelwelle beim Antrieb eines Gebläserades durch eine Reibungskupplung auszuschalten (DRP 704 851>. Damit werden zwar die Schwingungsausschläge gedämpft, deren völlige Ausschaltung ist jedoch nicht möglich, weil bei einer derartigen Ausfühbrung sowohl die Übertragungsfedern als auch die Reibkraft in der Kupplung auf das höchste auftretende Drehmoment ausgelegt sind.It is known to be used in drives for mass balancing second Order is the effect of torsional vibrations in the crankshaft when driving a fan wheel to be switched off by a friction clutch (DRP 704 851> Vibration deflections are dampened, but it is not possible to completely eliminate them, because in such a design both the transmission springs and the Frictional force in the clutch are designed for the highest torque that occurs.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.
Es zeigen Fig. 1 eine Frontansicht des Antriebes schematisch, Fig. 2 einen Schnitt nach Linie II-II der Fig. 1.Show it Fig. 1 is a schematic front view of the drive, FIG. 2 shows a section along line II-II in FIG. 1.
Auf der Kurbelwelle 1 ist das Antriebszahnrad 2 lose drehbar angeordnet. Uber die Kette 3 und die Kettenräder 4 und 5 werden die gegenläufig zueinander um-laufenden Hilfswellen 6, 7 mit den Gegengewichten 8, 9 angetrieben. Ein Rad 10, welches einstellbar gelagert ist, dient zur Veränderung der Kettenspannung.The drive gear 2 is loosely rotatably arranged on the crankshaft 1. About the chain 3 and the sprockets 4 and 5 are rotating in opposite directions to each other Auxiliary shafts 6, 7 driven by counterweights 8, 9. A wheel 10 which is adjustable is stored, is used to change the chain tension.

einem Ring 13 der Kurbelwelle oder bei zwei Reihen hintereinander an einem Zwischenring 14 befestigt sind. Wie bereits erwähnt, sind die Federn dabei derart abgestimmt, daß lediglich das bei konstanter Drehzahl auftretende Moment federnd aufgenommen wird, hingegen die Beschleunigungskräfte bzw. deren Momente durch Mitnehmerbolzen 15 an einem Flansch 16 der Kurbelwelle 1, welche in Langlöcher 17 im Antriebszahprad 2 greifen, übertragen werden. Zweckmäßiger.a ring 13 of the crankshaft or two rows behind one another are attached to an intermediate ring 14. As already mentioned, the springs are included matched so that only the torque occurring at constant speed Is resiliently absorbed, however, the acceleration forces or their moments by driving pins 15 on a flange 16 of the crankshaft 1, which in elongated holes 17 grip in the drive toothed wheel 2, are transmitted. More expedient.

Um die Nachgiebigkeit zu erhöhen, können zwei Reihen Drahtfedern hintereinander geschaltet vorgesehen sein, wobei die Zahl der Federn am Umfang den jeweiligen Bedürfnissen entsprechend durch Auswechseln veränderbar ist.are wise to increase the damping, the driving pins 15 with a elastic layer in the area of the elongated holes. To give in too increase, two rows of wire springs can be connected in series, the number of springs on the circumference according to the respective needs Replace is changeable.
